I know, my friend has an XP 1800 and it runs over 60, I was pleasently suprised to see mine running so cool. Look at my fans though:
2 intake case fans(bottom)
1 exhaust fan(back)
1 exhaust fan(top)
both HD's are in an actively cooled enclousure
copper CoolerMaster 6400RPM CPU fan
PSU fan
I'm gonna add another one or 2 in there somewhere...its pretty sweet

its sooo loud though.
